Pi x R squared. = area of a circle.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate the area of a circle use this formula: pi x r2.
the area of the circle is Pi X Radius squared
The area of a circle is: pi times radius squared

If its radius is in cm then the area of the circle is: pi*radius^2
A circle is two dimensional, it has area but not volume.
pi radius squared
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
The base of a cone is a circle. The area of a circle is found by multiplying the diameter by Pi.
